Seljenje RAID niza

[activated1]

Negde sam bio pročitao da je moguće, ali se ne sećam gde. Pa me zanima da li je moguće i kakva su iskustva. Ja sam napravio RAID0 od dva 500GB Samsunga za Steam library i generalno za instalacije igara, pošto jelte na SSD pored OS-a ako stane dve igre u današnje vreme puna kapa

E sad ako bi kojim slučajem menjao ploču, da li bi na novoj ploči bilo moguće rebuild-ovati taj RAID niz, jer iskreno izbagao bih redownload od jedno 300-400GB igara

Koliko se ja secam bese prica da mora da bude isti raid kontroler i tada su sasne male
Easus moze npr. da backapuje raid aray-a u image npr pa da to vratis na novi raid niz al ti treba hdd sa puno prostora(citaj 1tb)...

There is no widely-used "standard" for how RAID controllers handle the details of data storage on a pair of HDD's. This means that, as a general rule, when you try to move a pair of RAID0 HDD's from one machine to another, it is likely the new machine's controllers can NOT read or use the data on the old HDD's. You are left with only one option - wipe the HDD's clean and establish a new RAID0 array. Of course, this also means you lose everything on the drives. So, you MUST make a reliable complete backup of the original RAID0 array in the old machine BEFORE trying the move.

Now, sometimes it does work anyway. The odds of success are much better IF the RAID controller chip in the new machine is from the same chip maker as the old machine. That is because SOME RAID chip controller makers keep using exactly the same control algorithms, so their newer chips do everything the same as the older ones. HOWEVER, not all chip makers do this, so it's still a big risk. EVEN IF this is the case, there is also one thing that must be done correctly. In a RAID0 array, one disk is NOT the same as the other. So when the two are connected to the mobo ports, the "first" one (say, the one connected to SATA port #1) MUST be connected to the "first" position on the new mobo. This, too, is a bit of a shot in the dark sometimes, so it adds to the risk of failure.

Bottom line is that, although you MIGHT get it to work OK, you really should plan for it to fail. Make sure you have a good complete backup before starting. And then, also make sure you VERIFY that the backup is good and can actually restore everything to a new RAID0 array.

Ha znači ništa, realno nema potrebe da pravim image, mogu samo prekopirati sadržaj na drugi disk i vatiti nazad. Problem mi je prostor, gde da skladištim sadržaj sa tih diskova dok je selidba u toku. Druga opcija (za udubuće) je da koristim stand alone sata kontroler, onda selidba ne bi trebala da je problem, ali marvelov čip na tom kontroleru daje slabije performanse od AMD-ovog.
